Suppose an array “arrLongInt“ has 3 elements:

arrLongInt{1}:=1
arrLongInt{2}:=2
arrLongInt{3}:=3

You can use one of the following methods to reduce the size of arrLongInt to 0:

  ` Method 1: Redeclare the array to size 0
ARRAY LONGINT(arrLongInt;0)

  ` Method 2: Delete all elements in the array
DELETE ELEMENT(arrLongInt;1;Size of array(arrLongInt))

  ` Method 3: Copying an array with of 0 element to it
COPY ARRAY(<>emptyArrLongInt;arrLongInt)
